Description
Overview of the HPE P20499-001 Genuine Smart Memory Module
HPE P20499-001 is an 8GB DDR4 memory module designed for server applications. It is a registered ECC RDIMM module that operates at a clock speed of 3200MHz. This article will explain the technical specifications of the HPE P20499-001 memory module in simple English.
Memory Capacity and Configuration
The HPE P20499-001 memory module has a capacity of 8GB, which means it can store up to 8 gigabytes of data. It has a single rank configuration, which means that the module is populated with memory chips on only one side of the module. This configuration helps reduce power consumption and improve memory stability.
Memory Type and Speed
- The HPE P20499-001 is a DDR4 memory module. DDR4 stands for Double Data Rate Fourth Generation and is the latest memory standard for server and desktop computers. DDR4 memory is faster and more power-efficient than its predecessor, DDR3. The HPE P20499-001 operates at a clock speed of 3200MHz or 3.2GHz. This clock speed determines how quickly the memory can transfer data between the CPU and the module.
- Memory Latency and Timing Memory latency is the time delay between when the CPU requests data from the memory module and when it receives the data. The HPE P20499-001 has a CAS latency of 22, which is the number of clock cycles it takes to retrieve data after a request is made. The lower the CAS latency, the faster the memory module can respond to requests from the CPU.
- The memory module also has a timing specification of 22-22-22. This timing specification indicates the number of clock cycles it takes for the memory module to perform specific operations. The first number (22) represents the CAS latency, the second number (22) represents the RAS to CAS delay, and the third number (22) represents the RAS precharge delay. These timing specifications help optimize the performance of the memory module.
Memory Voltage
The HPE P20499-001 operates at a voltage of 1.2V. This voltage is lower than the voltage used by DDR3 memory modules, which typically operate at 1.5V. The lower voltage helps reduce power consumption and heat generation, which is critical in server environments where energy efficiency is important.
Memory ECC and Registered
The HPE P20499-001 is an ECC registered memory module. ECC stands for Error-Correcting Code, which is a technology that detects and corrects errors in the memory. This technology is critical in server environments where data accuracy is crucial. The registered technology allows the memory module to buffer memory requests, which reduces the load on the memory controller and improves memory stability.
Memory Form Factor and Pin Configuration
The HPE P20499-001 is an RDIMM module, which stands for Registered Dual In-Line Memory Module. RDIMMs are designed for server applications and have a higher capacity than standard DIMMs. The HPE P20499-001 has a form factor of 288-pin, which means it has 288 electrical contacts on its edge connector. The 288-pin configuration helps ensure that the memory module is compatible with the server’s memory slots.
Memory Brand and Authenticity
The HPE P20499-001 is a genuine HPE Smart Memory module. HPE Smart Memory is specifically designed and tested for HPE ProLiant Gen9 and Gen10 servers. It undergoes rigorous testing to ensure that it meets HPE’s high-quality standards. Using genuine HPE Smart Memory modules helps ensure system reliability and performance.
